Normal operation – Stage 2
When continuity is seen between B and C, the water valve de-energizes, the AUGER output (P4) comes on along
with the
MAKING ICE LED . The auger gearmotor’s start windings are energized through a current style start relay
that is pulled in by the initial high current draw of the gearmotor .
